ORIGINS OF MAGNESIUM
Magnesium is found in large amounts throughout our bodies. We obtain it predominantly from dietary sources. We can also obtain magnesium in many other places since it is the seventh most prevalent element from our universe. The earth’s crust contains large amounts of this element and we can obtain it from the minerals dolomite and carnallite. It is, however, most commonly extracted from our ocean waters. “Every cubic kilometer of seawater contains about 1.3 billion kilograms of magnesium”1 (Education).
There are many forms of magnesium found on earth. Magnesium Sulfate commonly known as Epsom Salt is one of many. We use several forms of the element for a variety of digestive issues. These include Magnesium Lactate, Oxide, Citrate, Carbonate and Sulfate. Magnesium Lactate has one of the highest rates of absorption out of these. Magnesium Oratate and Magnesium Glycenate are most readily used by our bodies and used by plant life as well. Magnesium Threonate is being touted as a newer type of supplement. It is considered superior to others on the market for mitochondrial interaction. When we obtain Magnesium from our diets it can be found frequently in high fiber foods. Additional food sources are plentiful. Since it is the seventh most common element of our earth’s crust it is common in foods we grow. Organically grown foods often have more magnesium since commonly used fertilizers do not add much magnesium. The magnesium in the ground where food is grown will have an effect on the content in the food. Some food sources most commonly referenced as good sources of magnesium are legumes, cruciferous vegetables, leafy greens (especially

spinach), seeds (sunflower, flax and pumpkin), nuts (especially almonds) whole grains (bran and quinoa) and even coffee and chocolate. Magnesium is also found in some spices, dairy and meats. Seafood such as Tuna, Mackerel or Halibut are good sources as well. We can even ingest magnesium from drinking water. It is especially prevalent in “hard water” which is found in wells and areas without a city water system. With all of the sources available it is hard to imagine but we often need supplements. It would not be unusual for someone to have magnesium deficiency despite all the ways we can ingest it.
Magnesium in the Body
Our bodies carry most of our magnesium in our bones, however, it is needed in every area of our body and for over 300 reactions we need in our normal functioning. So many functions are dependent on magnesium it would be nearly impossible to know them all. The most significant places for its use are in creation of ATP, our body’s energy source and proper formation of teeth and bones. About 50-60% of the magnesium stored in our bodies can be found in our bones. Regulation of our heart, blood pressure and heart function along with bowel function all depend on magnesium to work properly. It is not only important to keep our magnesium...
